摘要： There is provided a piezoelectric device for generating an acoustic signal in which an expansion mechanism expands a disposition of a laminated piezoelectric actuator by the principle of leverage. The mass of a base member placed in the expansion mechanism is larger than the mass of a vibration output member. An overall device size is small. The piezoelectric device has a pressurization structure for reducing a tractive force acting on the laminated piezoelectric actuator which is generated by the amplification. This enables provision of a piezoelectric device for generating an acoustic signal that is a small size, highly resistant to dropping impact, and has god acoustic performance with less sound leakage.

摘要： According to an embodiment of the present invention, a piezoelectric element composing a detecting part of a bone-conduction microphone is cantilevered by being mechanically pressed into an element mounting opening of a supporting member in a microphone case while temporarily bonded to a connecting member including a signal communication spacer, a copper-made spacer, a tapered ground spacer, and an insulating spacer, and optionally reinforced and fixed by use of an adhesive. Hence, it is possible to provide a cantilevered bone-conduction microphone having a vibration detecting part that can be assembled with a simple structure by use of an eco-friendly bonding material, not a solder.
